IMPROVEMENT IN WELL'AUGERS.

The Schedule referred. to intheuel Letters If'atent and makingpart'ofthe same..

To all whom it ana/y concern.-

Be it known that I, ELIJAH ALTMAN, of Handb' ton, in the county ofCaldwell andl State of Missouri,

have invented anew and useful Improvement in Welli Auger; and I dohereby declare 'that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art tomakeand use the same, Vreference being had to the accompanying drawingforming part of this specification'. Figure 1 is a side view of myimproved well-auger, partsheing broken away to show the construction.

Figure 2 is a top view of the same, partly in section through the linea: x, iig. 1.

Y Similarrletters of reference indicate corresponding parts.

My invention has for its object tofuruish an irnproved well-auger,designedv more particularly for bor-` ingthrough veins of 'quicksand,'and'whieh shall be simple in construction and e'ective in operation,taking outthe water and dirt much cleaner than angers constructed in theordinaryI manner; and

It consists in the constructiouaud combinationof the various parts ofthe auger, as hereinafter more full y described.

The conical point A of the lauger is rigidlyconfv nested4 with thelowe'r end of the shaft B, and ispreferably formed in one piece with thetube O. A

" D D indicate a double spiral-flange, securely attaehed to or formed on`and extending around the Vpoint A and tube C, on -opposite sides of thesame,

as shown. The office of these anges is the same as that ofthe lips andtwist or spiral anges of the ordi-- nary double-twistV wood-augers.

E is a disk, through the center of which, the shaft B passes, and whichfits loosely into the interior of the tube'G.

The disk E is connected with 4the disk F by rods, G, which rods shouldbe longer .than the tube O, so that when the disk E is in the bottom ofthe tub'e C the disk F may be above the uppel-end of the said tube, soas to leave -its upper end'wholly -unobstructed. I Y

To'the'disk-llare attached hooks, H, for convenn ienee in drawing thedisk E out of the tube O to clear it of dirt. l

Tot-he upper part of the shait B is rigidly :attached a disk, I, havingstaples or keepers, J, attached to its upper-side to receive levers foroperatingthe auger.

` The upperend of the shaft B, that projects above the disk I, should besquare o'for convenienceA in H, or equivalent, and disk I provided withkeepers J with -each other, substantially as herein shown and described,and for the purpose set forth. L
